Specifications

5.2 I/O Specs

Cable and connector specifications and connection examples for the Acquisition Trigger

input and the high-speed outputs are provided in the following sections.

5.2.1 Acquisition Trigger Input

The acquisition trigger input on the sensor is opto-isolated. To trigger from an NPN (pull-

down) type photo-detector or PLC output, connect pin 2 (TRG+) to +24V and connect pin 3

(TRG-) to the output of the detector. When the output turns ON, it pulls TRG- down to 0V,

turning the opto-coupler ON.

To trigger from a PNP (pull-up) photo-detector or PLC output, connect pin 2 (TRG+) to the

output of the detector and connect pin 3 (TRG-) to 0V. When the output turns ON, it pulls

TRG+ up to 24V, turning the opto-coupler ON.

62µSec maximum latency between leading edge of trigger and start of

acquisition. Input pulse should be minimum of 1 ms wide.

In-Sight 5403, In-Sight 5403S 66µSec maximum latency between leading edge of trigger and start of

acquisition. Input pulse should be minimum of 1 ms wide.

In-Sight 5000, In-Sight 5401 76µSec maximum latency between leading edge of trigger and start of

acquisition. Input pulse should be minimum of 1 ms wide.

NOTE:

When using the sensor with the Breakout cable, the polarity of the input trigger (pins 2 and 3)

is not critical. However, when using the optional Breakout or I/O Expansion Modules, the

polarity of the TRG+ and TRG- terminals should be observed.
